Abstract

La présente invention porte sur un procédé de contrôle du fer dans un processus hydrométallurgique. Le procédé peut comprendre les étapes consistant : à lixivier (14, 114) une bouillie d'alimentation (2, 102); à former une solution de lixiviation enrichie (12a, 12b; 112a, 112b); à enlever un premier résidu de lixiviation (18, 118) de la solution de lixiviation enrichie (12a, 12b); et à envoyer une partie (12b, 112b) de la solution de lixiviation enrichie (12a, 12b) et/ou du raffinat (22, 122) produit à partir de cette dernière, à un processus d'élimination de fer (34, 134). Selon certains modes de réalisation préférés, le procédé d'élimination de fer (34, 134) peut comprendre les étapes consistant : à traiter de façon séquentielle la solution de lixiviation enrichie (12a, 12b) et/ou le raffinat (22, 122) produit à partir de cette dernière dans un premier réacteur (Ri), un deuxième réacteur (R2) et un troisième réacteur (R3); à maintenir un niveau de pH du premier réacteur (Ri) au-dessus de 4, grâce à l'ajout d'une première base; à maintenir un niveau de pH du second (R2) et/ou du troisième (R3) réacteurs au-dessus de 8,5, grâce à une seconde base; et à former des solides (46) comprenant de la magnétite (68). Le procédé peut en outre comprendre les étapes consistant à effectuer une étape de séparation de liquide solide (36) après le processus d'élimination de fer (34, 134); et à effectuer une étape de séparation magnétique (64) pour éliminer la magnétite (68) desdits solides comprenant de la magnétite (68), sans limitation. La présente invention porte également sur un système permettant de réaliser le procédé.
